Abstract
A system for determining biomechanical properties of corneal tissue includes a light source configured to provide an incident light and a confocal microscopy system configured to scan the incident light across a plurality of cross-sections of corneal tissue. The incident light is reflected by the corneal tissue as scattered light. The system also includes a filter or attenuating device configured to block or attenuate the Rayleigh peak frequency of the scattered light, a spectrometer configured to receive the scattered light and process frequency characteristics of the received scattered light to determine a Brillouin frequency shift in response to the Rayleigh peak frequency being blocked or attenuated by the filter or attenuating device, and a processor configured to generate a three-dimensional profile of the corneal tissue according to the determined Brillouin frequency shift. The three-dimensional profile provides an indicator of one or more biomechanical properties of the corneal tissue.
